Just wondering everyone’s recommendations on cranking batteries? I have a 2016 Mercury Pro xs 175 and 2 HDS Carbons. Currently running a interstate group 31 w/ 950 cca and 195 rc that’s only 18 months old. I’ve been noticing my graph going dark while cranking and a slight hesitation at time coming out of the hole after fishing several hours. Local shop has had it numerous times and can’t figure out the problem. I’ve read that a weak battery can cause performance issues. Not sure if the 2 are related but I’m willing to replace the battery to see if it helps. Thanks
